摘要
为提高风-光的利用率,结合需求响应中的基于负荷率的实时电价模型与微电网优化运行模型,采用混沌烟花算法对微电网中需求侧负荷使用时间与电源侧微源的有功出力进行综合优化。Matlab仿真结果表明,当负荷曲线得到合理优化后,风-光的利用率有明显提升,微电网系统运行的经济性相应地也有所提升,验证该算法求解此类问题的可行性和精确性。
In order to improve the utilization rate of wind power and photovoltaic power,the micro-grid optimization operation model is combined with the real-time electricity price model based on load rate in demand response,and the chaotic firework algorithm(C-FWA)is used to optimize synthetically the load using time of demand side and the active power output of the power supply side in this paper.The simulation results with Matlab show that the utilization rates of wind power and photovoltaic power are improved obviously when the load curve is reasonably optimized,and the economy of the microgrid system is improved accordingly.Besides this,the validity and feasibility of C-FWA for solving this type of problem are verified.
